Exit Script
The exit script control statement stops script execution. It may be inserted anywhere in the script. An exit
script statement can be made conditional by the optional use of when or unless clause. The syntax is:
exit script[ (when | unless) condition ]
Where
condition is a logical expression evaluating to true or false.
Since the exit script statement is a control statement and as such is ended with either a semicolon or end-ofline,
it must not cross a line boundary.
Examples:
exit script
exit script;
exit script when a=1

First
The first prefix to a Load (page 246) or Select (SQL) (page 262) statement is used for loading just a set
maximum number of records from the data source, regardless of its length.
The syntax is:
first n( loadstatement | selectstatement )
where:
n is an arbitrary expressing which evaluates to an integer indicating the maximum number of records to be
read.
Examples:
First 10 Load * from abc.csv;
First (1) Select * from Orders; (Note: The parenthesis is allowed but
not required.)

For..next
The for..next control statement creates a loop with a counter. The statements inside the loop enclosed by for
and next will be executed for each value of the counter variable between specified low and high limits. The
syntax is:
forcounter = expr1 to expr2 [ step expr3 ]
[statements]
[exit for [ ( when | unless ) condition ]
[statements]
next[counter]
Where:
counter is a script variable name. If counter is specified after next it must be the same variable name as the
one found after the corresponding for.
